Pages and Posts issues

As of recently, cannot not change page/post status from passworded to public; cannot copy prior posts; cannot load media into pages/posts on any of the five blogs I manage.

THANK YOU! It is now working properly and I've got a new experience under my belt. If you are up for it, might you explain what changed that would cause this incompatability? This issue would have arise sometime between 9/17 and 9/25 (when I discovered it). Again, thank you for your advice and direction.

I'm on an old PC running Windows XP but I ditched IE years ago when it was IE6 (the worst browser wver!) . Currently I do have IE8 which I rarely use and only when I answer questions here. I also run Firefox 15.0.1 and Chrome 22 and I prefer FF.

okay. Because IE9 says I currently have a "newer version" and it won't download. I have Windows 7 64bit and this should work, but I don't understand why it says I have a newer version of IE9. Maybe I have to download ie8 first?

I use Firefox and Chrome, however, my husband likes IE. What to do. Maybe work on the W pages with an updated version of Firefox???

Hi there,
As your IE9 browser is no longer running in compatibility mode I wouldn't recommend that unless you do feel so inclined. If you do then to upgrade any browser version or download a new browser see here http://browsehappy.com

SimplyAlmond: When I downloaded the newest version of FF (15.0.1) the edit page came up, the links to work on the page were visible (previously I couldn't see the links across the top of the edit box) and it saved perfectly.
